I was checking out a new Colt A2 upper that I got, and I noticed this: the side of the mag well is slightly curved outward, on both sides, and when I mate it with a lower receiver, the walls stick out quite noticeably. Is this normal or is it faulty?

Don't have one of my uppers handy to look at, but I don't think there should be any bowing in the upper receiver. Here's a pic I borrowed from M60joe's site: and the receiver walls look pretty straight. |

It wont hurt, but if it bothers you, you can fix it. With strips of rubber or wood on both sides, use a large C-clamp to squeeze the sides in. Keep checking with your bolt carrier, NO OIL on carrier or inside the receiver, that it slides back and forth easily. You don't want oil masking any excess friction. Just squeeze in the sides a little at a time. |
Thanks for all your replys, I got this upper from a fellow member off of EE, he's a standup guy so I'm sure we'll be able to get things straighten out(no pun intended ). Here's another shot that I've taken, now it looks like the bowing isn't only on the magwell part, but along the entire length of the upper receiver

Yes indeed it really doesn't look right, hense I started this thread asking for your opinions. But that doesn't mean I want to hear unconstructive, smartass comments towards Colt such as the one posted by five5six and mjohn3006. All I'm asking is whether this is normal or a defect, so I could decided whether I should send it back or not, That's it. If you don't like Colt don't buy em, I don't wanna hear it. I appreciate all of you that have answered my question in a serious manner. |
